Vince was a very cool old guy so was Armand but if it is so damn cold that you have to wear a big ass sweat shirt... witf do you need to walk around in a thong?

Technically those aren't thongs, but men's "high cut briefs". And Vince was an eccentric anyway...If he could, he'd wear a Lion's pelt and walk around with a club and correct his clients with a swift hit to the hams.
